Note for 1.7.5.0. (1) If you find modules on the "BO - Modules" not showing correctly after upgrade to 1.7.5.0, some module's configure buttons and descriptions are missing. That's a cache related issue, you can fix it by removing the file in the \var\cache\dev\doctrine\cb\ folder. (2) Upgrade your "Products in the same category" to 1.0.4 after upgrade your site to 1.7.5.0. (3) Upgrade your Transformer theme to v4.3.2 and Panda theme to v2.4.2.

Upgrade your Transformer theme to v4.2.6 and Panda theme to v2.3.6 before upgrading your site to 1.7.4.0.

Upgrade your Transformer theme to v4.2.2 and Panda theme to v2.3.2 before upgrading your site to 1.7.3.1.
